In other instances, well-known devices may be shown in block diagram form to avoid obscuring the present disclosure. The various aspects of the present disclosure are not to be construed as limited to specific examples described herein but rather to include within their scopes all implementations defined by the appended claims.

FIG. 1 illustrates an example of a conventional cover plate 100, shown in a side view, which includes a mounting hole 120. It will be appreciated that the cover plate is generally fabricated from steel and has generally 90 degree edges on the entire perimeter.

FIG. 2 illustrates an example of a cover plate 200 (also referred to as a clamp bar in the art) shown in a side view, according to one embodiment disclosed herein. The cover plate 200 includes a first portion 210 that have sides which are at 90 degree angles, a mounting hole 220 and an angled portion 230 that may for example be in the range of 45 degrees. The cover plate in some embodiments may be formed from a ½ inch thick by 3 inch wide steel bar of a desired length to substantially cover the length of the plow blade. However, it will be appreciated that other materials may be used, such as other metals, metal alloys, high strength plastic materials, composites, etc. Additionally, it will be appreciated that the angled portion may be less or greater than 45 degrees. For example, in some applications the angle may range from 40 degrees to 50 degrees.

FIG. 3 illustrates an example of a plow assembly 300 including the cover plate 200 bolted to a conventional plow blade 310 and a backer plate 320 using one or more bolts (not illustrated). The backer plate 320 is bolted to the plow 350 using one or more bolts (not illustrated). In other embodiments, the cover plate 200, the plow blade 310 and the backer plate 320 may be bolted to the plow 350 using a common bolt (or multiple common bolts). The angled portion 230 of the cover plate 200 is facing down (i.e., toward the projection of the plow blade 310).

FIG. 4 illustrates a front view of the cover plate 200 having the first portion 210, one or more mounting holes 220, and an angled portion 230. The one or more mounting holes 220 are located in the first portion 210 and may be used to bolt the cover plate to the plow blade and the backer plate. The angled portion 230 of the cover plate is located opposite of a first side of the first portion (e.g., rectangular or square side of the bar that was not angled). As noted above, the cover plate is formed from a steel bar or any other suitable material. In one aspect, the steel bar has a cross section one half (½) inch by three (3) inches and a length of the steel bar is based on the length of the plow blade. Accordingly the length of the cover plate can have a length L, as shown in FIG. 4, that is substantially as long as the length of the plow blade. In some embodiments this will be a length of three feet or four feet to correspond to commercially available plow blades. In other embodiments, the cover plate can have a length that is less than the length of the plow blade. For example, two or more lengths of the cover plate may be used to cover the length of the plow blade. This may aid in the installation of the cover plate, since the weight will be reduced and the shorter length will be easier to handle and position.

Beveling the cover plate by having an angle on a portion the cover plate avoids the 90 degree corner that is present in the conventional cover plate 100 (see, e.g., FIG. 1). In operation, particularly, when the snow conditions have a lot of slush, the slush will hit the 90 degree edge of the conventional cover plate 100 and shoot out in front of the plow and over the top of the plow instead of following the contour of the plow and being projected out the end of the plow. This can cause problems such as icing of the lights, windows, radiators and other portions of the plow vehicle. It can also cause damage to the plow vehicle as the slush will also have abrasive material in the slush. Additionally, it reduces the operational efficiency of the plow vehicle as the operator will tend to use more washer fluid, wiper blades, tend to stop more frequently to address the icing and other related problems.

The cover plate 200 may have the bottom corner beveled at an angle (e.g., angled portion 230, which may be 35 to 55 degrees, and in some aspects 45 degrees) which prevents the slush (wet snow which may include debris) from being projected out and over the plow. The cover plate 200 improves the plow vehicle operator's ability to operate the plow vehicle because snow and slush is not coming over the plow and freezing on the windshield and lights, which can make it difficult to see. It will also reduce the purchase of washer fluid and wiper blades significantly, because there would be a reduction in the usage of wipers and wiper fluid. Further, more long term maintenance issues could also be reduced, such as replacing the wiper motor transmission, which runs the wipers and/or glass windshield due to scratching damage caused by materials in the slush. It will also help to reduce plow vehicles from overheating because slush would not be directed over the plow and therefor will not be packed into the radiators, which reduces air flow leading to overheating. Properly clearing the slush from the plow allows the plow vehicles to operate at proper speeds, which in return will increase the plowed lane miles per their shift and overall efficiency of the operations, which can lead to safer roads for travel. Other plow vehicle aspects can also be improved, such as the vehicle body condition, since the slush, dirt and other material getting thrown on the vehicle body will be reduced and related problems can be reduced, such as scratching the paint which causes increased rusting of the vehicle.

From the foregoing disclosure, it will be appreciate that various embodiments disclosed herein can include methods for fabricating the cover plate discussed in the foregoing. FIG. 5 is an illustration of a flowchart for forming the cover plate. According to various aspects disclosed herein, a method 500 includes, at block 510, forming a first portion of a cover plate. At block 520, one or more mounting holes are formed in the first portion of the cover plate. At block 530, an angled portion is formed on a side of the cover plate opposite from a first side of the first portion.

For example, a rectangular steel bar may be cut to a desired size to form the first portion and one edge of the steel bar may be ground down to the desired angle to form the angled portion. Mounting holes can be punched (to form generally rectangular holes) into the steel bar at desired locations to facilitate mounting to the plow blade, backer plate, etc. The holes may also, be drilled and/or machined to a desired configuration, which may include generally round, rectangular or square holes. Alternatively, the cover plate could be molded or cast from various materials, such as high strength plastic, various metals or composite materials. It may also be possible to weld the angle portion onto a metal bar. The welded portion could be ground or machined to a final product, if needed. Accordingly, it will be appreciated that the various aspects discussed herein regarding materials and or fabrication techniques are not exhaustive and are not intended to limit the scope of the various embodiments disclosed herein.
